Compilation performance

This document describes a systematic method for detection, isolation, correction and prevention of regression, on matters of compiler performance. The method focuses on the creation of small end-to-end scaling tests that characterize, and stand in for, larger codebases on which the compiler is seen to perform poorly. These scaling tests have a number of advantages over "full sized" performance-testing codebases:

An Operator's Look at RethinkDB

Matt Blair - @mattyblair - Flipboard

The Getting Started Experience

• It's in Homebrew and just runs (relative to, say, HBase): awesome!
• Having packages for popular Linux distros (I use Ubuntu personally and at work): awesome!
• Serving the GPG key over HTTP: not so awesome :-/
• apt-get -y install rethinkdb
• It didn't start by default- great! I hate when services do this. I then looked at the start script to see how it knew (usually daemons use /etc/default/blah, but it has custom logic to see if there's anything in /etc/rethinkdb/instances.d, which is cool).

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.
